Marco Your warrior looks great!! Lovong the finish youve done on it. And i understand what you mean by the barrel colour and the sleeve. Truly amazing work! Its inspiring me to get another warrior just hope mine can live up to the standards of your amazing work. keep up the good work look forward to your next project!

Regarding the canon color, as far as I could gather from the photos I've seen, it looks like very dark metal stain (that characteristic dark metal color). There is an area (close to the barrel sleeve) that is bright metal.

On the last photo, only the camouflage colors are applied (and the cannon is still to be painted as you correctly pointed out). I'm planning to brush paint all the details (like the cannon, fire extinguishers, etc...) using Vallejo Model Color range.

The paint work looks great!! Though ive noticed in observation that the 30mm rarden cannon end hasnt been painted or thats what it looks like in the photos its still the yellowish styrene colour. The wheels look great but the tracks are abit to brown in my opinion in comparison to the road wheels or are you planning to add mud effects? These are just my constructive observations the model looks great and cant wait to see your next stage of weathering keep up the good work.
